How Slate Stone behaves on a wall
Vista Paint publishes a light reflectance value of 68.9 for this shade. At LRV 68.9 this is a light shade that still carries colour rather than reading as off-white. It gives back most of the light in the room, which suits north-facing walls that need the help. For trim that reads as a clear edge rather than a smudge, aim about 30 LRV points away — roughly LRV 39 and below. Its red and blue channels are within a few points of each other, so it has no undertone worth naming — it takes its cast from whatever it sits beside. Order by the code, not the name, and put a test patch on the wall before you commit — a screen cannot show you how this shade behaves in your own light.
